Abstract

The invention discloses a DSP failure diagnostic system based on an immunity genetic algorithm, which consists of an FTU, a RTU, a DSP and an industrial controlling upper computer of a failure signal output display unit. The immunity genetic algorithm comprises the steps of: preparing a parameter code; setting an initial group; designing an adaptability function; setting a matching set; setting a controlling parameter; and solving iteration. The application of DSP failure diagnosis based on the algorithm comprises the steps of: taking the DSP as a core control process system; taking a discrete signal as an input signal of the DSP core control process system when the FTU and the RTU monitor the variable quantity of failure power frequency; and transferring a result which is obtained by the algorithm into a failure message in a practical system through the DSP core control process system to be showed on a monitoring upper computer. The invention has the advantages of: (1) solving the problem of the failure diagnosis of an electrical power system when a protection message is imperfect; and (2) inducing the application of an immune system-matching set to improve the whole searching capability of the algorithm.

Description

(1) Technical field: [0001] The invention belongs to the technical field of power system fault diagnosis, in particular to an immune genetic algorithm and a DSP fault diagnosis system based on the algorithm. (2) Background technology: [0002] Reliability is one of the basic requirements of power systems. However, due to the influence of various factors such as climate and man-made factors, the failure of the power system is inevitable. When the power system fails, operators are required to quickly determine the cause of the fault, remove the faulty components, and restore the normal operation of the system in order to reduce damage to the power equipment and ensure safe and reliable power supply to users. [0003] When the power system fails, the protection and circuit breaker may refuse to operate, malfunction, and the alarm information may be lost or distorted during transmission; there may be multiple faulty components. These all complicate the actual failure, and it is diffi...
